You can use a JOINKEYS application with a COPY or SORT operator
of ICETOOL, but not with any of the other ICETOOL operators. Use
the JKFROM operand instead of the FROM operand to indicate you are
using a JOINKEYS application.
If you want to sort the joined records, use a SORT operator with
USING(xxxx) in TOOLIN and a SORT control statement along with the
appropriate JOINKEYS, JOIN and REFORMAT statements in xxxxCNTL (main
task).
If you want to copy the joined records, use a COPY operator with
USING(yyyy) in TOOLIN and the appropriate JOINKEYS, JOIN and REFORMAT
statements in yyyyCNTL (main task).
For multiple JOINKEYS applications within a single ICETOOL step:
You can reference different JOINKEYS F1 and F2 input files for
the different SORT and/or COPY operators by using F1=ddname and F2=ddname
on the various JOINKEYS statements as appropriate
You can reference different subtaskn message and control files
for the different SORT and/or COPY operators by using TASKID=id on
the various JOINKEYS statements as appropriate.
